New study shows multiple factors joined forces to devastate the Great Barrier Reef in 2016.

Global warming has affected the entire planet’s surface, except for one particular area of the ocean, which until 2015 had bucked the trend. A research team has now unraveled what was going on.

Freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

Biologists are using footage from remotely operated vehicles to better understand where deep-sea octopuses prefer to live. Understanding an animal’s choice of habitat is crucial to understanding its life history. Abigail Pratt, a biologist at the University of Louisiana at Lafayette, has been crawling through undersea video footage from the North Atlantic Ocean to better understand where deep-sea octopuses prefer to settle down. Pratt is hoping to find out what seafloor features make the best real estate – whether octopuses prefer hard ground or soft, or whether they tend to settle on specific geographical features like submarine canyons or continental shelves.

Both sea ice retreat and global warming could be slowed by millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers have now, for the first time, tested the concept using a complex climate model.

Convection in Earth’s mantle is the “engine” driving plate tectonics. Hot material rises to the Earth’s surface from the boundary between the planet’s core and mantle, at a depth of about 3000 kilometers. Cold material then flows downward due to oceanic tectonic plates sinking into the mantle at subduction zones on the Earth’s surface.

Particulate organic matter from the open ocean has a bigger-than-expected role in the growth and health of coral reefs, say researchers studying declining coral reefs in Hawaii.

New research explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S. The answer is complex, according to a study published Aug. 6 in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union.

New research shows that injecting air and carbon dioxide into methane ice deposits buried beneath the Gulf of Mexico could unlock vast natural gas energy resources while helping fight climate change by trapping the carbon dioxide underground.

A new study explains the mechanism behind Hurricane Harvey’s unusual intensification off the Texas coast and how the finding could improve future hurricane forecasting.
